Which Pokémon Will get New Forms/Evolutions in Legends Z-A?

Pokémon Legends Arceus was a breath of fresh air, and everyone loved the fact that we saw NEW regional forms and even evolutions in the game! And now that we have Pokémon Legends Z-A on the horizon I think it's safe to say that we'll find at least a few new variants and an evolution or two in this alternate version of the Kalos region! Also Mega Evolutions are confirmed to come back so that should be factored in as well!
